David Marcus served the State of Oregon as an ALJ (Administrative Law Judge) for more than 28 years. As an arbitrator or mediator, he has resolved over 1000 disputed construction claims, including numerous six-figure and multi-party cases. As an ALJ, he has entered orders in more than 600 additional claim cases, after conducting a contested case (administrative) hearing. Mr. Marcus' cases have included both commercial and residential construction claims, brought by homeowners, commercial and government property owners, subcontractors, employees, and material/equipment suppliers, and have involved all of the following issues: excavation, erosion, irrigation and drainage; concrete, masonry and paving; water supply systems, septic and waste disposal systems; plumbing, electrical and HVAC, including radiant heat, solar and other passive systems; siding (including stucco), roofing (wood, asphalt, tile, metal) and painting; and, hazardous materials, including lead paint, asbestos, and mold.

Mr. Marcus has also handled a significant number of cases involving real estate sales and financing contracts for new and existing homes and businesses.

Recent cases (2014) have included: a dispute between seller and buyer over refund of six-figure earnest money in a failed sale of a $1,000,000 property; and, a dispute over a national residential contractor’s unilateral change to specifications during construction of an upper end new home.

In addition, Mr. Marcus currently serves (since 2013) as a facilitator/mediator for the Oregon Foreclosure Avoidance Program, assisting defaulting owners and their lenders to resolve the default with an agreed upon foreclosure avoidance measure.
